Bleeding for days after sex while on depo?

I had sex Saturday and I bled a bit after and on Sunday I bled a bit more and now it's Wednesday and I'm still bleeding, I have to wear a pad. Is this normal? I've also been on depo provera since April of 2014

By now, I would have expected your periods to have stopped all together, but sometimes after you've been on Depo for a while, you get breakthrough bleeding, especially after intercourse. The way that stopped me having any bleeding, was to have the next couple of shots brought forward to around 9 & then 10 wk intervals. After that, I could go back to having them at the normal interval, & had no bleeding at all.
